Abstract: The report contains measured values of the thermal conductivity and the electrical resistivity, as well as the (total) Lorenz functions L(T) calculated from them in the temperature range 273-1500 K by two precision methods on 43 pure metals. Two precision measuring methods were brought into operation. Except for the data for six alkali and alkaline-earth metals determined by Cook et al. according to the NRCC method, all other data were determined according to the direct heating method developed from 1982 at KFA Jülich. Apart from closing various gaps in knowledge concerning thermal conductivity, for example with the noble metals, lanthanides and some other metals, including Y, Hf, Re, V, Zr and Ti, the special feature of the present report is a regular behavior found for the Lorenz functions L(T) not previously known for high temperatures. On the basis of previous conceptions, an approximation to the Sommerfeld value of L$_{0}$=2.44$\cdot$10$^{-8}$ V2/K2 was generally expected. However, a grouping within five approximately equidistant bands was found, covering the range from 2.15 to 3.15$\cdot$10$^{-8}$ V2/K2.
